Field guides for backing up virtual machines, testing restores, and keeping copies that survive the production site.
Guides
Keep an off-site virtual machine backup
A second copy in the same rack still shares power, cooling, and a fire. Send one copy to another site or a separate account.
Read guideTest a virtual machine restore
A backup counts only after you boot a copy on storage and a network that cannot reach production.
Read guideMake application-consistent virtual machine backups
Ask the guest to flush databases before the hypervisor copies disks, or the restored machine may boot with a torn write.
Read guideBack up Proxmox virtual machines
Use vzdump or the backup server so each Proxmox guest has a copy outside the disk that holds its virtual disk.
Read guideBack up Hyper-V virtual machines
Protect Hyper-V guests with a job that uses the Hyper-V VSS writer, stores the copy off the CSV, and can import the virtual machine on another host.
Read guideQuestions
Are the guides written for one vendor?
No. Each hypervisor has its own article, and the practice articles apply across VMware, Hyper-V, and Proxmox.
Can I search in my language?
Yes. Search from the header only returns pages in the language you are reading.
How many guides are on each page?
The index lists six guides per page. A second page appears when more than six guides exist.
